It disappears. That's pretty much it.

What about adding a "Quest Log" after a ship returns from a quest? It would contain some inside jokes and humor, along with seriousness. A bit like The Battle Cats, actually. Also, I would like for ships to sometimes enter galaxies and steal technologies, destroy other ships, then fly away, etc, with the explanation that they're questing ships from another galaxy.
This is why I suggested adding an option to turn them off. I don't like them appearing out of thin air to remove dragon infestations. They'll keep themselves in control anyways due to infighting.
There's the occurence I call the "Marauder Train". The Marauders all spawn in the same position and follow the same movement pattern, so if many are spawned in a quick succession, there will be a large train of destruction that spews missiles everywhere while traversing long connections. I urge you not to remove this, it's hilarious.
They often ignore enemy ships flying right past them, but also often fly to the other side of the galaxy at breakneck speeds to kill some random maintenence ships. They also tend to lock on to ships that are on a quest and camp near the galaxy border.
